WAGON-WRENCH.

SPECIFICATION, forming part of Letters Patent No. 567,561, datedSeptember 8, 1896. Application filed October 29, 1895. Serial No.567,333. (No model.)

To all whom, it may concern.-

Be it known that we, ERNEsr A. BAYER, FRANK NUEss, andFREDERIOKSOHAFFITZEL, citizens of the United States, and residents ofKansas City, in the county of Jackson, State of Missouri, have inventedcertain new and useful Improvements in lVagon-Wrenches, of which thefollowing is a specification.

Our present invention relates to a simple device for removing andputting back nuts from the axles of wagons by the swing of the wheel incases where the ordinary wrench will not suffice.

All the details of the device are represented in Figure 1, which shows aportion of a wheel to which is applied the wrench in condition forworking. Fig. 2 is a different view of one of the details on a littledifferent scale. Fig. 3 is another view of the frame E, shown in Fig. 1.

A is the hub, and B the spokes, of the wheel.

0 is the nut which holds the wheel upon its axle.

D represents the jaws of the wrench, and are shown clamping the nut O,and are pivoted between the sides of the frame E, so that their ends maybe adapted to fit upon nuts of different sizes within reasonable limits.The jaws project beyond the frame E, measured from the nut, and aregrooved on one side to receive the conical wedge G. (Shown dotted.) Thegrooves are located at H. The conical wedge G is carried at one end ofthe screw 1, and the crank J at the other end. The screw passes throughthe nut K. The said nut K is carried by and pivoted to arms L, which arepivoted to opposite sides of the nut K, and they are also pivoted to twoconnectingrods L, which are hooked at the outer ends and thereby claspthe spokes B. The connecting-rods L pass between the the sides of theframe E.

The operation of the invention may be stated as follows: Place the rodsL so as to clasp the opposite spokes B in the manner represented in Fig.2, and place the jaws D upon opposite sides of the nut 0. Then turn thecrank J. It will cause the wedge G to pry open the outer ends of thejaws D and to press the other ends with great force upon power andtherefore-becomes loosened.

The advantages of the wrench are, in short, as follows: If desired, thedevice may be retained on the wheeland will keep the nut tight in thewheel in thesame position, so that it has no chance to fall down on theground and get full of sand or mud. A person need not take hold of thenut with his hand and get his fingers all full of axle-grease. It can beused on buggies, carriages, spring wagons, farm or any other heavywagons, as it makes no difference if the hub is small or large or if thenut has six instead of four sides, as is often the case. It usuallytakes a man only half the time to grease a wagon with this wrench.

WVe claim as our invention- A wagon-wrench, consisting of thecombination of connecting-rods L, for clasping the spokes of a givenwheel, a rectangular frame, between whose sides are pivoted jaws forclamping the nut upon the axle of the wheel and extending beyond theframe where there are grooves in the jaws, a conical wedge located inthe grooves and carried at one end of the screwI which is provided witha crank at the other end, a nut through which passes the said screwand'to which are pivoted arms L, connecting with the rods L that passthrough said frame.
